MSDS
Extinguishing Media: Carbon Dioxide, Dry Chemical, Foam, Water Fog
Unusual Fire And Explosion Hazards: None known.
Special Firefighting Procedures: Cool fire -exposed containers using water spray.
Steps To Be Taken If Material Is Released Or Spilled: Wear proper protective equipment as specified in Section 8.
Scrape up dried material and place into containers.
Handling: KEEP OUT OF REACH OF CHILDREN! Avoid contact with skin and eyes. Do not breathe dust. While dry
sanding, use of a NIOSH-approved dust mask is recommended. Removal of this product after use will result in the
generation of Dust. If dry-sanded, exposure to dust may result in the build-up of material in eyes, ears, nose, and mouth
which may cause irritation. Avoid excessive heat and handling. Wash thoroughly after handling.
Storage: Avoid excessive heat and freezing. Do not store at temperatures above 120 degrees F. Keep tightly closed.
Store away from caustics and oxidizers.
Exposure Notes:
14808-60-7 The 2002 ACGIH Threshold Limit Values for Chemical Substances and Physical Agents lists the median
Respirable Particulate Mass (RPM) point for crystalline silica at 4.0 microns in terms of the particle's aerodynamic
diameter.
The TLVs for crystalline silica represent the respirable fraction.
OSHA PEL TWA for Quartz is calculated using the following formula: 10 mg/m3/(% SiO2 + 2). Both concentration and
percent quartz for the application of this limit are to be determined from the fraction passing a size selector with the
following characteristics.
|------------------------------------------------------------------------------------|-----------------------------------------|
| ....... Aerodynamic diameter ( unit density sphere ) .....| Percent passing selector |
| 2 ................................................................................|.................90....................|
| 2.5 .............................................................................|..................75...................|
| 3.5 .............................................................................|..................50...................|
| 5.0 .............................................................................|..................25...................|
| 10 ..............................................................................|...................0....................|
Precautionary Measures: Please refer to other sections and subsections of this MSDS.
Engineering Controls: Local ventilation of emission sources may be necessary to maintain ambient concentrations
below recommended exposure limits. Prevent build-up of dust and vapors by opening windows and doors or use other
means to ensure fresh air entry during application, drying and sanding. Wet sanding is recommended to avoid generation
of dust.
Respiratory Protection:
If concentrations exceed the exposure limits specified, use of a NIOSH
